In your onCreateView() you need to show a ProgressBar, since your webView.loadUrl(url) takes time to load the internet content on your WebView. So you need to register for a call back when your WebView is done loading your content. You can listen like this :

mWebView.setWebViewClient(new WebViewClient() {

   public void onPageFinished(WebView view, String url) {
        // Cancel your ProgressBar here
    }
});

Inside your onPageFinished() cancel your ProgressBar since your WebView has completed loading the content.

WORKING CODE

public class MainActivity extends Activity {

    private String url = "https://www.google.co.in/";
    ProgressDialog pb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        pb = new ProgressDialog(this);
        pb.setTitle("Connecting Station");
        pb.setMessage("Please Wait....");
        pb.setCancelable(false);
        pb.show();
        WebView webView = (WebView) findViewById(R.id.webView);
        WebSettings webViewSettings = webView.getSettings();
        webViewSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        webViewSettings.setJavaScriptEnabled(true);
        webViewSettings.setPluginState(PluginState.ON);
        webView.loadUrl(url);
        webView.setWebViewClient(new WebViewClient() {

            public void onPageFinished(WebView view, String url) {
                pb.dismiss();
            }
        });
    }
}
